		<h1>[name]</h1>

		<p class="desc">
			A loader for loading an [page:Image] as an
			[link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap ImageBitmap]. An ImageBitmap provides an asynchronous and resource
			efficient pathway to prepare textures for rendering in WebGL.<br />
			Unlike [page:FileLoader], [name] does not avoid multiple concurrent
			requests to the same URL.
		</p>

		<p>
			Note that [page:Texture.flipY] and [page:Texture.premultiplyAlpha] with
			[link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap ImageBitmap] are ignored.
			[link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap ImageBitmap] 
			needs these configuration on bitmap creation unlike regular
			images need them on uploading to GPU. You need to set the equivalent
			options via [page:ImageBitmapLoader.setOptions] instead. Refer to
			[link:https://www.khronos.org/registry/webgl/specs/latest/1.0/#6.10 WebGL specification] for the detail.
		</p>

		<h2>Code Example</h2>

		<code>
		// instantiate a loader
		const loader = new THREE.ImageBitmapLoader();

		// set options if needed
		loader.setOptions( { imageOrientation: 'flipY' } );

		// load a image resource
		loader.load(
			// resource URL
			'textures/skyboxsun25degtest.png',

			// onLoad callback
			function ( imageBitmap ) {
				const texture = new THREE.CanvasTexture( imageBitmap );
				const material = new THREE.MeshBasicMaterial( { map: texture } );
			},

			// onProgress callback currently not supported
			undefined,

			// onError callback
			function ( err ) {
				console.log( 'An error happened' ); 
			}
		);
		</code>

		<h2>Examples</h2>

		<p>[example:webgl_loader_imagebitmap WebGL / loader / ImageBitmap]</p>

		<h2>Constructor</h2>

		<h3>[name]( [param:LoadingManager manager] )</h3>
		<p>
			[page:LoadingManager manager] — The [page:LoadingManager loadingManager]
			for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].<br /><br />

			Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Loader] class for common properties.</p>

		<h3>[property:Boolean isImageBitmapLoader]</h3>
		<p>Read-only flag to check if a given object is of type [name].</p>

		<h3>[property:String options]</h3>
		<p>
			An optional object that sets options for the internally used
			[link:https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/createImageBitmap createImageBitmap] 
			factory method. Default is `undefined`.
		</p>

		<h2>Methods</h2>
		<p>See the base [page:Loader] class for common methods.</p>

		<h3>
			[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )
		</h3>
		<p>
			[page:String url] — the path or URL to the file. This can also be a
			[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
			[page:Function onLoad] — Will be called when load completes. The argument
			will be the loaded [page:Image image].<br />
			[page:Function onProgress] (optional) — This callback function is
			currently not supported.<br />
			[page:Function onError] (optional) — Will be called when load errors.<br />
		</p>
		<p>
			Begin loading from url and return the [page:ImageBitmap image] object that
			will contain the data.
		</p>

		<h3>[method:this setOptions]( [param:Object options] )</h3>
		<p>
			Sets the options object for
			[link:https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/createImageBitmap createImageBitmap].
